Line charts are one of the most basic and widely used tools in crypto trading. They show the price movement of a crypto asset over a given time frame, usually on a linear or logarithmic scale. 

Read below and learn how to read and use line charts in crypto trading, and how they help you identify trends, among other advantages.

How Are Line Charts Used in Crypto Trading?

Line charts play a crucial role in helping crypto traders analyze historical price data and predict future price movements. Each data point on a line chart represents the closing price at a particular time interval, like minutes, hours, days, or weeks. These data points are then connected by lines that form a continuous visual representation of price movement.

Here are some key ways in which line charts are used in crypto trading:

  1. Identifying trends

 Line charts make it easier to identify trends in the market. By observing the direction and slope of the line, you can determine whether the price is generally trending upwards (bullish) or downwards (bearish). This information can guide trading strategies like trend-following or trend-reversal.

  1. Spotting support and resistance 

Line charts help traders identify support and resistance levels. Support represents the price level at which buyers tend to enter the market and prevent further price declines, while resistance is the price level at which sellers become dominant, preventing further price increases.  You can use these levels to determine entry and exit points for your trades.

  1. Determining entry and exit points 

Line charts allow traders to spot patterns and chart formations that indicate potential entry and exit points. For example, a trendline breakout or a reversal pattern may provide signals for entering a trade or closing an existing position. By analyzing the historical price data presented in line charts, you can make more informed decisions regarding market entry and exit.

  1. Comparing cryptocurrencies 

Line charts are invaluable for comparing the price performance of different cryptocurrencies. By overlaying multiple line charts on the same graph, traders can visually assess the relative strengths or weaknesses of various cryptocurrencies. This comparison helps in choosing the most favorable assets for trading or investment.

Using Line Charts With Technical Indicators

Line charts are particularly useful for tracking long-term trends and identifying key support and resistance levels. They provide a simplified view of price action without the noise of intraday fluctuations, allowing traders to focus on the bigger picture.

However, line charts are not just about price tracking. They can be used to display other crucial market indicators that help in making informed trading decisions. Here are three common indicators often represented as lines (a deeper explanation of these indicators is done in the Technical Indicators chapter):

1. Moving Averages (MA)

Moving averages smooth out price data over a specified period, making it easier to spot overall trends. By comparing short-term and long-term moving averages, traders can potentially identify favorable buying or selling conditions. 

Prices that move below moving averages usually indicate bearish trends, while price action that’s above moving average lines shows a bullish trend. One thing to keep in mind when trading line charts with moving averages is that you’ll usually see an even balance between the moving average and the support or resistance price level. Additionally, the bigger the time frame, the stronger support or resistance gets.

2. Relative Strength Index (RSI)

The Relative Strength Index (RSI) is a momentum indicator that shows the speed and change of price movements. When plotted as a line, it oscillates between zero and one hundred, helping traders identify overbought (RSI value over 70) or oversold conditions (RSI value below 30).

Additionally, the RSI can help confirm the strength of an existing trend. In a strong uptrend, the RSI line should generally stay above 50, and in a strong downtrend, it should generally stay below 50.

3. Bollinger Bands

Bollinger Bands consist of a middle band and two outer bands that indicate volatility and potential price reversals. The middle band, representing a moving average, can be displayed as a line chart, aiding in the understanding of price volatility. 

Bollinger Bands can help you in timing your entries and exits. For instance, when you identify an uptrend on the line chart, wait for the price to touch or cross the upper Bollinger Band as a confirmation of an overbought condition before considering a sell order.


To sum up, line charts are an indispensable tool in the crypto trading arsenal. By understanding what line charts are and how they are used, you’ll gain valuable insights into price trends, support and resistance levels, and potential entry and exit points. 

Incorporating line chart analysis in your trading strategies can significantly improve your trading strategy by tracking price movements in cryptocurrency markets. 

Along with key market indicators like Moving Averages, RSI, and the middle band of Bollinger Bands, line charts provide crypto traders with a richer analytical toolkit for better decision-making.
